In case anyone was wondering, why yes, it is possible for a stealthy rogue poop nugget to survive both the wash and dry cycles.
If this happens, you will be left with something that looks like a cross between a raisin and a pebble. You may even pick it up and put it on top of the dryer while you empty the rest of the clothes. You will then turn your attention back to said 'raisin' and pick it up out of curiosity...sort of an "ooh, look what happens to a raisin after being in the the washer and dryer, the wrinkles are all gone, and it's hard as a..." And you may then stop and get a whiff of something...funky.
And then, you just may put said raisin-rock hybrid up to your nose and about fall over backwards at the stink of it...the stink of...OMG, it's poop!
You will then have to rewash the entire load of clothes again. And scrub your hands for a really long time afterwards.
Yep, that's me...boldly going where you haven't so that you won't have to.
Consider yourselves warned :)
